If you need to enter your estimated tax payments in TurboTax, please follow the steps below. In addition, it is important that you enter the state (Pennsylvania), date paid and amount paid for each quarterly payment made. I have attached a picture below for guidance. 

You can follow these steps to enter your payments: 

1. Open your tax return.
2. Search for estimated tax payments with the magnifying glass tool on the top of the page. 
3. Click on the Jump to estimated tax payments link at the top of the search results.
4. Click on Start next to State estimated taxes for 2020.
5. Select yes for the question Did you pay state estimated taxes for 2020?
6. Follow the on-screen instructions.
